I'd like to create a time-boxed project to apply what I've learned about [concept]. 
Could you design a 30-minute exercise that:

1. Focuses specifically on applying [specific aspect or technique]
2. Produces a tangible result I can evaluate
3. Relates to my goal of [your broader learning objective]
4. Can be completed with the tools and resources I have available
5. Includes clear evaluation criteria so I know if I've understood correctly

Please make this practical rather than theoretical, and ensure it's genuinely completable within the time limit.
